Quizbank/College Physics Sem 1
This quizbank is LaTeXbased
In order to implement this upgrade, much of this effort is being moved to
https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home/
The conversion to LaTeX should make this bank more compatible with VLEs
If you have Python and LaTex you can actually begin to use this system!

College Physics Sem 1[edit]
This unit has 5 exams (tests) that can viewed by clicking the links (e.g., T1). They are classroomready exams based on the collection of quizzes shown below each exam. The fraction indicates the ratio of the number of questions randomly selected to the number of questions on each quiz. Students can access these quizzes using either the (uneditable) permalink or directly via links to subpages of QB. Students and instructors can also view all at /All. Ideas for use by instructors can be found at Quizbank/Instructions.

Measured in radians, defines angle (in radians), where s is arclength and r is radius. The circumference of a circle is and the circle's area is is its area. The surface area of a sphere is and sphere's volume is
A vector can be expressed as, , where , and are the x and y components. Alternative notation for the unit vectors include and . An important vector is the displacement from the origin, with components are typically written without subscripts: . The magnitude (or absolute value or norm) of a vector is is , where the angle (or phase), , obeys , or (almost) equivalently, . As with any function/inverse function pair, the tangent and arctangent are related by where . The arctangent is not a true function because it is multivalued, with .
The geometric interpretations of and are shown in the figure. Vector addition and subtraction can also be defined through the components: AND
01Introduction

 1 kilometer = .621 miles and 1 MPH = 1 mi/hr ≈ .447 m/s
 Typically air density is 1.2kg/m^{3}, with pressure 10^{5}Pa. The density of water is 1000kg/m^{3}.
 Earth's mean radius ≈ 6371km, mass ≈ 6×1024
kg, and gravitational acceleration = g ≈ 9.8m/s^{2}  Universal gravitational constant = G ≈ 6.67×10−11
m^{3}·kg^{−1}·s^{−2}  Speed of sound ≈ 340m/s and the speed of light = c ≈ 3×10^{8}m/s
 One lightyear ≈ 9.5×10^{15}m ≈ 63240AU (Astronomical unit)
 The electron has charge, e ≈ 1.6 × 10^{−19}C and mass ≈ 9.11 × 10^{31}kg. 1eV = 1.602 × 10^{19}J is a unit of energy, defined as the work associated with moving one electron through a potential difference of one volt.
 1 amu = 1 u ≈ 1.66 × 10^{27} kg is the approximate mass of a proton or neutron.
 Boltzmann's constant = k_{B}≈ 1.38 × 10^{23} J K^{−1} , and the gas constant is R = N_{A}k_{B}≈8.314 J K^{−1} mol^{−1}, where N_{A}≈ 6.02 × 10^{23} is the Avogadro number.
 ≈ 8.987× 10^{9} N·m²·C^{−2} is a fundamental constant of electricity; also ≈ 8.854 × 10^{−12} F·m^{−1} is the vacuum permittivity or the electric constant.
 = 4π × 10^{−7} NA ≈ 1.257 × 10^{−6} N A (magnetic permeability) is the fundamental constant of magnetism: .
 = h/(2π) ≈ 1.054×10^{−34} J·s the reduced Planck constant, and ≈ .526 × 10^{−10} m is the Bohr radius.
Two dimensional kinematics
Difference is denoted by , , or the Delta. or . Average, or mean, is denoted by , where is number and are probabilities. The average velocity is , and the average acceleration is , where denotes position. In CALCULUS, instantaneous values are denoted by v(t)=dx/dt and a=dv/dt=d^{2}x/dt^{2}.
The equations of motion for uniform acceleration are: , and, . Also, , and, . Note that only if the acceleration is uniform.

...in advanced notation this becomes .
In free fall we often set, a_{x}=0 and a_{y}= g. If angle is measured with respect to the x axis:
The figure shows a Man moving relative to Train with velocity, , where the velocity of the train relative to Earth is, is the velocity of the Train relative to Earth. The velocity of the Man relative to Earth is,
If the speeds are relativistic, define u=v/c where c is the speed of light, and this formula must be modified to:
